Some thing to try What ever works fer u.

Yes thanks Kerry, have used that but I like the way hot melt gives you a chance to wriggle it around a bit to get the both sides perfectly aligned.
Aha. Gotcha on the pics.

Rather than work with a lot of difficulty I sliced off the left side of the nose to make it easy to remove the motor. Why not? It is a quick, easy & strong repair with hot glue.

Another method to change the motor angle is to put some small washers behind the motor mount on two of the screws.

This is what I usually do. That way you can test it out and make adjustments if needed.

My Fox is very gentle on stall at 50mm, nothing odd happens,just drops nose and continues to fly after that.. I am surprised at how slow the airframe can actually fly. Landings are almost hands off....just keeps the wings level. I took the time to balance it laterally as well.

Thanks rhawk, good to know on the stall. I have balanced also so should be the same. I was too busy enjoying the flat glide you gave me , slows right down and just floats past. Looks nice about 6' up, sliding by.

Did you find the ailerons more sensitive as the C/G is moved back?

OK, thanks Glen. I'll take a look at that before I glue her back together

Here is what I am going for to give max. visibility

I know it is a bit like pattern style but I hope to be getting this girl up to quite some altitude when we can get our summer back from you guys.

Good to hear it worked for you!

Well, I maxed out my aileron throw at the same time I moved the CG back, so I cant really say if it was the CG affecting it or not, but they did get way more responsive with the added CF on the TE. Im only able to get big barrel type rolls out of the Fox.....is this your experience?

I had a blast last nite catching thermals as the Sun went down at the end of a breezy 90 degree day. I swear I was trurning flat 8 foot circles with full rudder, some aileron, and up elevator. Lots of fun!

Anyone got a picture of how their motor/spinner looks after adding some down thrust? I am about to glue mine back together and want to make sure I have enough angle on it.

Hey Rob
Big slow rolls is all I can get even with the flat C/F on the ailerons, max throws rearward C/G and rudder. I added the C/F and moved C/G at the same time.

When doing this, do you use rudder to turn and opposite aileron to keep it flat ?? I have heard this but have not seen a thermal as yet.

I try to do that as much as possible when slope soring.

Thanks Glen, so it does work.
I haven't tried it yet but I have tons of rudder so it should be able to do it.

Forgive me, as this is my first glider, and I was pretty giddy at the thermal action.....I THINK I used aileron as usual to initiate the turn, and then opposite to keep it flat.

Lots of rudder makes the nose want to go down, so it needs some up elevator along with opposite aileron.

Hey Glenn, Should we be using some aileron differential on the Fox? (less down than up)
